Quantum optical technologies for metrology, sensing and imaging
Jonathan P. Dowling, Kaushik P. Seshadreesan
Over the past 20 years, bright sources of entangled photons have led to a renaissance in quantum optical interferometry. Optical interferometry has been used to test the foundation…
Rényi squashed entanglement, discord, and relative entropy differences
Kaushik P. Seshadreesan, Mario Berta, Mark M. Wilde
In [Berta et al., J. Math. Phys. 56, 022205 (2015)], we recently proposed Renyi generalizations of the conditional quantum mutual information of a tripartite state on (with $…
Fidelity of recovery, geometric squashed entanglement, and measurement recoverability
Kaushik P. Seshadreesan, Mark M. Wilde
This paper defines the fidelity of recovery of a quantum state on systems , , and as a measure of how well one can recover the full state on all three systems if system $…
Sampling arbitrary photon-added or photon-subtracted squeezed states is in the same complexity class as boson sampling
Jonathan P. Olson, Kaushik P. Seshadreesan, Keith R. Motes +2
Boson sampling is a simple model for non-universal linear optics quantum computing using far fewer physical resources than universal schemes. An input state comprising vacuum and s…
Renyi generalizations of the conditional quantum mutual information
Mario Berta, Kaushik P. Seshadreesan, Mark M. Wilde
The conditional quantum mutual information of a tripartite state is an information quantity which lies at the center of many problems in quantum information th…
Boson sampling with displaced single-photon Fock states versus single-photon-added coherent states---The quantum-classical divide and computational-complexity transitions in linear optics
Kaushik P. Seshadreesan, Jonathan P. Olson, Keith R. Motes +2
Boson sampling is a specific quantum computation, which is likely hard to implement efficiently on a classical computer. The task is to sample the output photon number distribution…
